Use OS X Photo Copy and Paste Settings for Quick Editing
Whether it’s macros or something else, most photo editing kits have all sorts of tricks for quick photo editing. Apple Photos doesn’t have these gimmicks, but Macworld shows it has a handy copy and paste feature that’s easy to miss.
After you finish editing a photo in the Photos app, you will probably realize that you have other shots that look similar. You can easily apply all the adjustments you make to one photo to another by pressing Command + Shift + C to copy the settings, then switch to a new photo and press Command + Shift + V to paste it. The changes you make to the first image are applied to the second. Photos aren’t as powerful as the Pixelmator , but it does have a few tweaks up its sleeve. Visit Macworld for some more tips.
